As anticipation builds for Artemis II—the mission set to return humans to the Moon for the first time since the Apollo 17—attention is often focused on rockets, astronauts, and deep space technology. Yet, one critical component remains firmly grounded on Earth: the launch pad. Designed to withstand some of the most extreme thermal and mechanical conditions imaginable, launch pads rely on advanced refractory materials to ensure safe and successful liftoffs.
For nearly 70 years, HWI, A member of Calderys has played a vital role in supporting the space flight industry with innovative refractory solutions. This legacy dates back to 1958 with the launch of Explorer 1, America’s first satellite, where refractory technology was already essential in protecting launch infrastructure from intense heat and exhaust erosion.
As space exploration evolves, so too do the demands placed on launch and landing systems. Modern missions like Artemis require materials that can endure higher thrust, longer burn times, and increased launch frequency. HWI continues to meet these challenges by developing next-generation refractory products and technologies tailored specifically for aerospace launch pad and landing pad applications. These solutions not only enhance durability and safety but also contribute to faster turnaround times between launches—an increasingly important factor in today’s space economy.
To dive deeper into the critical role refractories play in spaceflight, explore HWI’s special space-focused edition of High Temperature Times™. Our podcast, dedicated to all things high temperature, is available on platforms like iTunes, Google Play, and Spotify. In this special episode, we break down the science, engineering, and real-world applications behind launch pad refractory systems, offering unique insights into the technology that supports every successful liftoff.
As humanity prepares to take its next giant leap, it’s clear that innovation on the ground is just as important as exploration in the skies. With decades of expertise and a continued commitment to advancement, HWI remains a trusted partner in helping launch the future of space exploration.
